If you have a noisy appliance in your home, you know how it can be frustrating to live with humming or vibrating machines. Dishwashers, specifically, can make it difficult for you to enjoy the tranquility of your home.

However, this shouldn’t be a worry to you anymore.

In this article, we will discuss with you simple techniques you can apply to reduce the noises you will experience from your dishwasher.

Inspect and Fix the Noise Source

If your dishwasher was quiet, but all over sudden it starts making a lot of noise, there could be some problem with it. Before trying any soundproofing technique, get it checked. If you find any problem, then let a technician fix it.

Here are some of the common problems that could cause your dishwasher to be noisy.

Malfunctioning Pump

The role of the pump is to operate the spray arms and draining dirty water from the dishwasher. It has a filter and impeller located at its bottom.

Therefore, if you hear noises coming from the bottom of your dishwasher, the pump could be the problem. Check any debris or dirt stuck on it. Clean it and ensure nothing it’s blocking the pump.

But if this doesn’t fix the pump’s noise, get an experienced technician to check it further and determine what the problem could be.

If it’s not debris causing the problem on your pump, you might opt to replace the pump. Ask help from a professional to get the right pump and fix it over your pump.

Loose Seals and Broken Bearings

A loose seal will make your dishwasher make some rattling sounds. If you hear such noises coming from the dishwasher, inspect the seals.

Bearings, too, will make similar noises when they are broken.

Seals and bearings break and wear out easily since they are made of plastic. And if you find they are the reason your dishwasher is making noises, all you need to do is to replace them. If you aren’t sure about the bearings and seals to buy, get help from an experienced technician. A qualified dishwasher technician will help you get and fix the best bearings and seals on your dishwasher.

Broken or Worn Out Spray Arms

Spray arms need to be working properly without straining. However, when they are broken or worn out, they don’t rotate correctly.

Worn out spray arms will definitely make noises.

Check them regularly. If you notice any problem with them, buy new ones. Get the arms replaced and enjoy washing your dishes with all the quietness you need.

2. Remove and Replace Your Dishwasher InsulationDishwasher Insulation

A dishwasher comes with sound and heat insulation over it. Most dishwashers have either soundproofing blankets or foams. And just like any other material in your dishwasher, the insulations wear out.

As the insulation starts wearing out, their effectiveness reduces.

The older the insulation gets, the lesser effective it becomes. If you have used your dishwasher for a long time, get a technician to replace the insulations for you.

But if you are confident enough, remove the insulation on yourself. It’s usually attached to the dishwasher with a rivet. Use needle-nosed pliers to remove the rivet. You will need to reuse it over the new blanket you will install.

Here is a dishwasher insulator that will work for most of the brands in the market.
